A blob is any kind of content that is stored by a Registry under a content-addressable identifier (a "digest").-
- Layers are a good example of "blobs". -
-An image is a named set of immutable data from which a Docker container can be created.-
- An image is represented by a json file called a manifest, and is conceptually a set of layers. - - Image names indicate the location where they can be pulled from and pushed to, as they usually start with a registry domain name and port. - -
-A layer is a tar archive bundling partial content from a filesystem.-
- Layers from an image are usually extracted in order on top of each other to make up a root filesystem from which containers run out. -
-A manifest is the JSON representation of an image.
A namespace is a collection of repositories with a common name prefix.-
- The namespace with an empty prefix is considered the Global Namespace. -
-A registry is a service that let you store and deliver images.-
A repository is a set of data containing all versions of a given image.-
A scope is the portion of a namespace onto which a given authorization token is granted.
A tag is conceptually a "version" of a named image.-
- Example: `docker pull myimage:latest` instructs docker to pull the image "myimage" in version "latest". -

There was an implementation of the Registry API V1 but only a version 0.9 of the service was released. -The image formats are not compatible in any way. One must convert v1 images to v2 images using a docker client or other tool. -One can migrate images from one version to the other by pulling images from the old registry and pushing them to the v2 registry. - ------ - -The Docker Registry 2.0 is backward compatible with images created by the earlier specification. If you are migrating a private registry to version 2.0, you should use the following process: - -1. Configure and test a 2.0 registry image in a sandbox environment. - -2. Back up up your production image storage. - - Your production image storage should reside on a volume or storage backend. - Make sure you have a backup of its contents. - -3. Stop your existing registry service. - -4. Restart your registry with your tested 2.0 image. diff --git a/Godeps/_workspace/src/github.com/docker/distribution/docs/mirror.md b/Godeps/_workspace/src/github.com/docker/distribution/docs/mirror.md deleted file mode 100644 index feb2630c..00000000 --- a/Godeps/_workspace/src/github.com/docker/distribution/docs/mirror.md +++ /dev/null @@ -1,72 +0,0 @@ - - -# Registry as a pull through cache - -## Use-case - -If you have multiple instances of Docker running in your environment (e.g., multiple physical or virtual machines, all running the Docker daemon), each time one of them requires an image that it doesn’t have it will go out to the internet and fetch it from the public Docker registry. By running a local registry mirror, you can keep most of the redundant image fetch traffic on your local network. - -### Alternatives - -Alternatively, if the set of images you are using is well delimited, you can simply pull them manually and push them to a simple, local, private registry. - -Furthermore, if your images are all built in-house, not using the Hub at all and relying entirely on your local registry is the simplest scenario. - -### Gotcha - -It's currently not possible to mirror another private registry. Only the central Hub can be mirrored. - -### Solution - -The Registry can be configured as a pull through cache. In this mode a Registry responds to all normal docker pull requests but stores all content locally. - -## How does it work? - -The first time you request an image from your local registry mirror, it pulls the image from the public Docker registry and stores it locally before handing it back to you. On subsequent requests, the local registry mirror is able to serve the image from its own storage. - -### What if the content changes on the Hub? - -When a pull is attempted with a tag, the Registry will check the remote to ensure if it has the latest version of the requested content. If it doesn't it will fetch the latest content and cache it. - -### What about my disk? - -In environments with high churn rates, stale data can build up in the cache. When running as a pull through cache the Registry will periodically remove old content to save disk space. Subsequent requests for removed content will cause a remote fetch and local re-caching. - -To ensure best performance and guarantee correctness the Registry cache should be configured to use the `filesystem` driver for storage. - -## Running a Registry as a pull through cache - -The easiest way to run a registry as a pull through cache is to run the official Registry image. - -Multiple registry caches can be deployed over the same back-end. A single registry cache will ensure that concurrent requests do not pull duplicate data, but this property will not hold true for a registry cache cluster. - -### Configuring the cache - -To configure a Registry to run as a pull through cache, the addition of a `proxy` section is required to the config file. - -In order to access private images on the Docker Hub, a username and password can be supplied. - - proxy: - remoteurl: https://registry-1.docker.io - username: [username] - password: [password] - -> :warn: if you specify a username and password, it's very important to understand that private resources that this user has access to on the Hub will be made available on your mirror. It's thus paramount that you secure your mirror by implementing authentication if you expect these resources to stay private! - -### Configuring the Docker daemon - -You will need to pass the `--registry-mirror` option to your Docker daemon on startup: - - docker --registry-mirror=https://
